Space X Rocket Launch Fails

Launching rockets remains dangerous. A Space Exploration rocket blew up on launch, two minutes and 14 seconds into its flight on June 28, 2015.  It was traveling about one kilometer per second at an altitude of 40 kilometers.

Eventually, as new constellations of low earth orbit satellites begin to happen, there is some risk of failure as well. The fact that dozens of LEO satellites can be launched from one rocket ensures the potential destruction of a large number of satellties from any single launch failure. 

Historically, a reasonable forecast might be a two percent failure rate for launches. Others might estimate failures at five percent.
